was, with his co-adventurers, carrying on a business. It is true the
business was in a measure limited in point of capital, and was not
intended to endure indefinitely ; but neither of those circumstances
is inconsistent with carrying on a business. The all-important fact
is that there were a series of transactions connected by a common
purpose, that of dealing in wheat scrip, and consisting of all the
characteristic operations found in a business of that nature, buying
and selling ; the scrip itself being treated, not as an investment, but
as stock-in-trade, a mere medium for successfully carrying through
the profit-making scheme. The capital invested was risked, and was
returned, with the profit it had earned. I have no doubt the Com-
missioner is right and the question should be answered accordingly.
I will add a word to prevent possible misconception : - What I
have said has reference to the facts of this particular case, in which
the only claim made by the Commissioner is on the basis of income
derived from personal exertion. The appellant resisted on the
ground that the adventure was not a " business " within the meaning
of that term as found in the definition of "income from personal
exertion." I have expressed the opinion that it was. But nothing
I have said must be taken as indicating that, if the adventure had
not been a "business" and the Commissioner had assessed the
profits as income from property, he would have failed. Whatever
is "income" is income from property, unless it falls within the
statutory definition of "income from personal exertion." A mere
realization of property though producing profit does not, as I have
said, produce income. It is a mere enlargement of capital. But if
a man, even in a single instance, risks capital in a commercial
venture - say, in the purchase of a cargo of sugar ora flock of sheep -
